: Application filed June 21,

To all whom it may concern: 3 Be it known that I, THOMAS EDWARD DAY, a subject of the King of Great Britain, residing in Belleville, in the county of Essex and istate of New Jersey, have invented certain new and useful Improvements in Squeezers, of which the following'is a specification.

My present invention relates. to squeezers such as are commonly used to' squeeze or work masses of puddled iron to remove the slag'and to consolidate the mass. 1

In certain types of puddling furnaces, the puddled iron ball is very much larger than it is whenmade in the generally used puddling furnace known as the hand furnace,

and it also often takes a relatively longer form, somewhat cylindrical in shape. The squeezers ordinarily used for balls of puddled iron cannot be conveniently used when the product is greater in weight, say, above two hundred pounds, and when the form it takes is peculiar in shape as aforesaid.

One of the objects of my invention is to devise a squeezer which will handle masses of puddled iron of the character described, so that the same may be don'e'quickly and certainly in anoperation where the loss of a few, seconds of tim will seriously afi'ect the subsequent operations.

lVith this and-other objects in View, my invention consists in the constructions and arrangements hereinafter described, and more specifically pointed out in the appended claims.

In't'he drawings, Figure 1 is a central sectional elevation of an illustrative embodiment of my invention; Fig. 2 is a plan of the machine shown in Fig. 1;Fig. 3 is a central vertical section of Fig-.1 with some of the parts omitted and broken away, and Fig. dis a detail showing a modification.

The same reference characters refer to the I same parts in the several views.

In'th illustrative form of my invention, a scroll is formed of a plurality ofbed pieces 1d, each having its ends resting on lips 12 and 13 of a pair of side members and 11. The edges of each piece may be slightly recessed between the lips to form spaces 15, asshown in Fig. 3, through which the slag mayflow. If desired, additional openings 1.6 may be provided through the bed pieces for the same purpose. The-surfaces of the bed piecesmay be corrugated or roughened,

in the usual manner:

1921. Serial No. 479,183.

In the side members 10 and .11 are journaled the bearings of a roll 17 this roll beingpositioned so that a channel is formed between the scroll and the surface of the roll, with one end of the channel wider than the opposite end, as is usual in squeezers. The surface of the roll may also be corrugated in the usual manner, and may also be provided with larger projections or dogs, if desired. The roll 17 may be rotated in any convenient manner, as by the gears 18, 19 attached to the shaft of the roll. The means for driving these gears is not shown, but it will be understood that they may be driven in any suitable manner.

It is necessary that the cylindrical mass of puddled iron shall be fed through the channel at its wide end, so that the axis of the mass will be approximately parallel to the axis of the roll 17. It is also necessary that this soft, spongy mass shall not be permitted to fall or drop suddenly into the channel, in order to prevent its being wedged into the space before the roll 17 has had an opportunity to begin to rotate and squeeze the mass. I, therefore, provide means by which the mass may be guided and lowered slowly, and preferably at a regulated speed, into the channel.

As one convenient arrangement to accomplish this purpose, I have provided a tilting table 20, pivoted on a shaft 21, and preferably supported on a part of the frame of the machine. The table 20 is normally positioned, as shown in Fig. 1, with its inner end extending across the wide end of the channel and sloping downward towardthe roll 17. In order to hold the table 20 in this position whil sustaining the weight of the puddled mass, I provide a holding device, such as a latch 22 engaging a toe 23 on the table 20. The shaft 21, in the illustrative form, is provided at each end with a sheave 2%, over which passes a cable 25,

to which is attached a weight 26. Preferably this weight is made up of a number of pieces, so that its weight may be adjusted to suit the operating conditions.

Th frame of the machine is cut away, as at 27, so that the table 20 may be swung clockwise with the shaft 21 until the table 20 lies within the space 27, out of the channel.

As a guiding means for the mass, I have illustrated a pair of guides 28, 29, pivoted to swing downward, but the speed at which it moves will be regulated by the lifting of the weights 26. This will permit the mass to move slowly. down into the ,channehthe table swinging into the space 27 to permit it to pass; The mass will then be gripped between the scroll and the roll 17 and will be squeezed, in the usual manner, as it passes through the channel. The slag squeezed out will pass out through the openings 15 and 16. When the compacted mass has reached the right-hand, or narrow, end of the channel, its further progress will be stopped when the end of the channel is reached, and in orderto remove the mass, from the squeezer,

the upper end ofthe dog.

7 I perferably provide a dog 32, pivoted at 38, and preferably supported on the frame of the machine, the dog preferably extending across the spacebetween the side members 10. and 11. v

Preferably the dog 32 is weighted, so that it normally lies inthe full-line position shown in Fig. 1. The inner face 3 1 of the dog. 32 is preferably formed 'so that when the dog has swung to the dotted-line position in Fig. 1, the face 341- will constitute a continuation of the channel face of the scroll. When the dog is in the dotted-line position a toe 35 will contact with some part, such as the top of the frame of the macnne, so that it cannot be rotated any further on the pivot 83. i

. lVith the parts shown in full-line posi tion in Fig. 1, the squeezed mass will be forced up until it contacts with the face 3% of thedog 32, which will thenv be rotated to the dotted-line position of Fig. 1, and, by reason of the continued pressure on the mass, it will be forced up until it passes The dog will then swing downward on its pivot 33 until it is again in the full-line position in'Fig. 1, and when in this position, the top or upper side of the dog will constitute a kind of platform, down which the finished mass may roll or be otherwise moved out of the machine.

If desired, instead of using the dog 32, I may use the'arrangeme'nt shown in Fig. 4, in which aseries of slots 1 are provided across the frame of the machine, so that a bar 41 may be inserted beneath the mass as it reaches the narrow end of the scroll and 'ith the surface of the roll 17. The latch 22 is then tripped and the weight of the mass causes the table 20 be used'to force it outof'tlie squeezer, to be removed therefrom.

r In order to prevent the finished mass from being forced over the top of theroll 1-7, I prov1deastop42. 7 5 V It will be understood that the arrangement which I have shown is merely illustrative,

may be widely Varied.
